Coyne, of Oklahoma City, was on a trip to Los Angeles on Nov. 10 when a TSA agent spotted a hand-grenade in his bag at a security checkpoint.

The agent closed the checkpoint and began protocols for dealing with a live bomb. The TSA explosives expert was not on duty at the time but quickly arrived and determined the grenade, painted gold, had been deactivated and posed no threat. According to police reports, Coyne said the grenade, which had a hole in the bottom, was a gift given to him at a party in Arkansas.

The west security checkpoint was closed. While people in line behind Coyne missed flights during the one-hour security delay, most were rebooked and sent on their way.

Coyne tweeted an apology and posted a photo on Twitter next to the etched-glass depiction of the Flaming Lips at the airport, along with a status update.

“Sorry Sorry Sorry! Everyone that was inconvenienced because of my grenade at OKC airport!!” Coyne wrote on Twitter.

Since then, the story has been twisted all sorts of ways by websites everywhere.

Kevin Donovan, TSA's federal security director for Will Rogers, described the incident.

“One checkpoint was closed for less than an hour, not the whole airport,” he said in a phone interview Tuesday afternoon. “Our Transportation Security Specialist-Explosives guy was not on-site. He got there and cleared everything up.”
